I am planning a trip from Berlin to Dresden, would like to know if it's better to travel by train or air? If so, which airline flies from berlin to dresden? coz i searched the net and couldn't figure out...

Of course you couldn't figure out - why should an airline fly the 180 km distance?
You have a choice of train or train (or rental car of course but this doesn't make sense either).

www.bahn.de

It's two and a quarter hours by train. I can't imagine why anyone would want to fly.

The only reason people wouldn't want to fly is because the rail service is so good. This isn't that different a distance than between Washington, DC, and Philadelphia, or LAX and SAN and people fly between those two pairs of cities all the time

Did you try www.airberlin.com. Or try www.whichbudget.com

I flew Air Berlin last summer from Zurich to Berlin one-way. Great service, cheap price, nice flight attendants, free food and drinks and a roomy leather seat.

Hi
We drove from berlin to Dresden last year. It took about 90 minutes. The hotel had a parking lot so we had a place to leave the car. Very convenient.

There are a number of EuroCity trains per day that make the trip from Berlin Hbf to Dresden in 2:11 for 32 EUR per person. Other trains take close to 3 hours and cost more.

However, if there are two or more of you, for just one hour longer (3:14), you can take regional trains and save at least 27 EUR.

You use a Brandenburg ticket at 23 EUR (for up to 5 people) to Prösen, then 6,80 EUR per person from there to Dresden.
